Cadaver is an open source GNU GPL free webdav client. It is useful to access your idisk for example, or possibly other web sites. It works from a terminal. There is no GUI. I am not the author of this app - all I have done is compile this on Zeta R1. Now enabled SSL.
This is a must have program for people using LinkSys Cable/DSL routers. If you do not have said router, this program will be of no interest to you (except maybe if you need source code examples) This was developed to watch the broadcast data from a linksys router and report it back to you.
